Love is painful. Never resist, never create any barrier for pain. Allow it. And by and by you will see that it was a wrong interpretation.
It is not really pain. It is just that something is going so deep in you that you interpret it like a pain. You don't know anything else.
You are only aware of pain in your past life, in your past experience. Whenever something penetrates deep, you interpret it as pain.
Don't use the word 'pain'. When love and love's arrow goes deep into your heart, close your eyes and don't use words — just see what it is, and you will never see it is pain.
You will see it is a benediction. You will be tremendously moved by it. You will feel joyous.
Don't use words.
When something new happens to you, always allow a deep look into it without any language.
